M&A activity snapshot
Some of the largest distribution deals of 2025 were in building materials, and all three below were made by public companies. QXO completed its acquisition of Beacon Roofing Supply at $124.35 per share, about $11 billion, making it, in QXO's words, the largest publicly traded U.S. distributor of roofing, waterproofing, and complementary building products. Home Depot, through SRS Distribution, completed its purchase of GMS for a total enterprise value of about $5.5 billion. Lowe's agreed to buy Foundation Building Materials for $8.8 billion in cash.
Sector-wide deal counts dipped and then recovered. Capstone Partners counted 351 building products transactions in 2025, down 10.9% year over year, and 182 in 2026 through mid-year, up 28.2%. Those counts include manufacturers. Under NAICS, lumber and wood panel distribution is code 423310. The broader group, lumber and other construction materials merchant wholesalers, reported $301.7 billion of sales in 2024, down from $324.0 billion in 2022, according to Census data.
Who is buying
Home-improvement retailers chasing the professional contractor. Lowe's said FBM would help it serve the large Pro planned spend within a $250 billion total addressable market. Home Depot bought GMS through SRS, which operates more than 800 locations across 48 states under distinct local brands.
Public distributors and installer-distributors. TopBuild acquired Specialty Products and Insulation for $1.0 billion in cash, adding about 90 branches. Installed Building Products completed 11 acquisitions in 2025 representing over $64 million of annual revenue and expects to acquire at least $100 million of annual revenue in 2026. BlueLinx bought Disdero Lumber, a two-step specialty distributor, for about $96 million.
Platform builders. QXO describes building products distribution as an $800 billion industry it plans to lead, a signal that it intends to keep acquiring.
What buyers look for
Professional contractor relationships. The strategic logic behind the largest deals is access to pro customers who buy repeatedly and in volume, as both Lowe's and Home Depot framed their purchases.
Commodity-adjusted earnings. Builders FirstSource says wood product prices directly affect its sales and earnings, and lumber and lumber sheet goods made up 26% of its 2025 net sales. Buyers separate commodity gains from operating performance and price on a normalized year.
End-market mix. A distributor tied only to new single-family construction carries more cycle risk than one with repair and remodel volume. Harvard's Joint Center for Housing Studies projects remodeling spending growth slowing to 0.5% year over year by the second quarter of 2027, so buyers are testing both sides of the mix.
Specialty categories. Every large deal above was for a specialty distributor: roofing (Beacon), wallboard and interior products (GMS, FBM), insulation (SPI), and two-step specialty products (Disdero), rather than a commodity lumber yard.
What makes a strong company
A building materials distributor that commands a premium typically shows:
- A large and loyal base of professional contractors, with no single builder or project carrying the business.
- Earnings that hold up when lumber and panel prices are normalized.
- Specialty product lines (roofing, insulation, millwork, engineered wood, interior products) rather than mostly commodity lumber.
- Branch locations and a delivery fleet that cover a market densely enough to serve job sites quickly.
- A mix of new construction and repair and remodel demand.
Valuation and deal structure
Multiples have risen. Capstone reports building products M&A multiples averaged 10.6x EV/EBITDA from 2025 to mid-2026, more than a full turn above the 9.4x 2024 average, and that the median deal size rose from $185 million to $411.6 million. This covers the full sector, not distribution alone.
Deal-level multiples show the size gap. Capstone lists Home Depot/GMS at 10.2x EBITDA and QXO/Beacon at 10.7x. Lowe's paid 13.4x adjusted EBITDA for FBM, calculated net of about $300 million of expected tax benefits, on $635 million of 2024 adjusted EBITDA. At the smaller end, BlueLinx paid approximately 7 times trailing 12-month EBITDA for Disdero, on a pro forma basis after expected cost savings and tax benefits. No major provider publishes a lower-middle-market multiple for building materials distribution alone. For a general starting point, see the Axia valuation tool.
The large 2025 deals were cash purchases by public acquirers. Earnouts and seller rollover are common in private-equity deals generally, but the sources above do not report their use in this vertical.
Outlook
The 2025 megadeals removed several of the largest independent targets, so the next 12-24 months are likely to favor regional and specialty bolt-ons. Installed Building Products has guided to at least $100 million of acquired revenue in 2026, and Capstone notes that sector participants have outlined strong M&A pipelines for 2026. The main risk is demand: slowing remodeling spending and lumber price swings will weigh on how buyers underwrite trailing earnings.
